Building without --enable-server but with --enable-proxy breaks the build.

The reason is that src/zabbix_server/vmware/libzbxvmware.a isn't built if you don't build the server but linked to the proxy binary, as far as I can tell.

The remaining flags are as follows, but should not matter:

--enable-dependency-tracking
--enable-agent
--enable-ipv6
--disable-java
--with-net-snmp
--with-ldap
--with-libcurl
--with-openipmi
--with-jabber
--with-unixodbc
--with-ssh2
-with<database-backend>
